Plant development displays a remarkable degree of plasticity and continuously adjusts to the plant's surroundings, a process that is triggered by the perception of environmental cues such as light and temperature. Transcription factors of the PHYTOCHROME-INTERACTING FACTOR (PIF) family have long been established as key negative regulators of light responses; within the last decade, increasing evidence suggests that they are also core components of temperature signalling, and multiple mechanisms by which temperature regulates activity of these transcription factors have been discovered. It has become clear that these temperature responses cannot be considered in isolation, but that they occur in the context of, and are influenced by, other environmental signals. This review discusses recent advances in the understanding of the mechanisms through which temperature affects PIF function and how these mechanisms are influenced by the light environment.
植物发育表现出显著的可塑性，并不断根据植物周围环境的变化进行调整，这个过程是由对环境线索（如光和温度）的感知触发的。长期以来，PHYTOCHROME-INTERACTING FACTOR（PIF）家族的转录因子一直被认为是光反应的关键负调控因子；在过去的十年中，越来越多的证据表明，它们也是温度信号转导的核心组成部分，并且已经发现了多种温度调节这些转录因子活性的机制。现在已经很清楚，不能孤立地考虑这些温度反应，而是要在其他环境信号的背景下并受其影响。本综述讨论了在理解温度影响 PIF 功能的机制方面的最新进展，以及这些机制如何受光环境的影响。
